Does the lunar calendar only have a leap month every few years? How many leap months are there in th

The time is uncertain, sometimes once every two years, sometimes once every 3-4 years, irregular.

The lunar calendar is a lunisolar calendar: its years are divided into ordinary years and leap years. Twelve months in a normal year; Leap years are thirteen months. The months are divided into big months and small months.

There are thirty days in the big month and twenty-nine days in the small month.

Its average calendar month is equal to one synodic month. Which month of the year is older and which is smaller is determined by calculation.

Advantages of the lunar calendar:

1.The lunar calendar is a lunisolar calendar, which takes into account the relationship between the sun, the moon and the earth. The lunar calendar is a fixed calendar, which has the characteristics of an astronomical calendar, and can correspond well to various celestial phenomena, such as its solar terms strictly correspond to the height of the sun.

The calendar day corresponds more strictly to the phases of the moon.

The frequency of non-occurrence and occurrence of leap months correspond to the perihelion and aphelion of the Earth.

Other celestial phenomena such as sunrise and sunset, morning and dusk shadows, five-star orientation, solar and lunar eclipses, tides, etc., and even the calendar months roughly correspond to the height of the sun.

2.There are only 29 days and 30 days in the lunar calendar month, and they are stipulated by the fixed date, and the human factor is small, and it is not easy to change at will.

3.The beginning of the year has strong astronomical significance, and has the astronomical significance of the lunar month and the yang year.

The leap month of the lunar calendar is one leap in 3 years, two in 5 years, and seven in 19 years.

The Chinese lunar calendar divides the 24 solar terms into 12 solar terms and 12 middle terms. The lunar calendar is based on the moon cycle (lunar calendar), and the 12-month calendar has a total of about 354 days. Combined with the almanac (Gregorian calendar), the almanac is based on the cycle of the four seasons formed by the rotation of the earth.

The monthly calendar is shorter than the annual calendar, with a difference of 11 days, so it is necessary to add 7 more leap months every 19 years to fill in the error.

There are seven leap months every 19 years in the lunar calendar. It depends on which year there is a leap month or which leap month it is.

The leap month of the lunar year is every two or three years, or more precisely, there are seven leap months in every 19 years on average.

Biennial or triennial.

There is a general method of "seven leaps in 19 years" among the people. On the lunar calendar, since the total number of days in the 12 months of a common year is 11 days less than that of the solar calendar, the calendar stipulates that every two or three years, a leap month must be added to make up for the difference of about one month. And since this difference is not a regular number, it is not very regular to add a leap month in any year.

However, with the increase of years, people have summed up a law of "seventeen years and seven leap laws", that is, in nineteen years, China's lunar calendar should roughly have seven leap months in the year. In the end, it is appropriate to add a leap month after which month depends on the difference between which month and the 24 solar terms, because the 24 solar terms of the lunar calendar are basically consistent with the date of the solar calendar. However, under normal circumstances, there is no leap month after the wax month and the first month of the lunar calendar.

1.The order of the day is determined by the phases of the moon. It calculates the date and time of the conjunction of the sun and the moon one by one, and the first day of the month is the date of the conjunction; The size of the previous month is determined according to the number of days included in successive double conjunctions.

If the interval between this conjunction and the next conjunction is 30 days, then that month is the Great Moon; If it is only 29 days apart, it is a small month.

2.The order of the month is determined by the middle air. First of all, we know that a return year has 12 solar terms, but it contains a synodic month, and after several calendar month rotations, there must be a calendar month without a neutral month.

The Hanshu Legal Calendar contains: "Shuo is not in the middle, it is called a leap month". This month without a neutral air is a leap month.

It is a leap month when the previous calendar day is a month.

The lunar calendar is not called a leap year, but a leap month, which is generally seven leaps in 19 years, and there will be an average of one leap month every two or three years.

The folk lunar calendar has a leap once in many years, and seven leaps in 19 years.

The time is uncertain, sometimes once every two years, sometimes once every 3-4 years, irregular.

The lunar calendar is a lunisolar calendar: its years are divided into ordinary years and leap years. Twelve months in a normal year; Leap years are thirteen months.

Months are divided into major months and minor months, with the major month having 30 days and the minor month having 29 days, and its average calendar month is equal to one synodic month. Which month of the year is older and which is smaller is determined by calculation.

Lunar leap months are generally held once every three years.

In order to reconcile the contradiction between the return year and the lunar year.

Hello <>

Expand the information for you: Leap month is a kind of calendar with intercalary squares. In Asia, especially in China, a leap month refers to a month that increases every 2 to 3 years in the lunar calendar.

In order to reconcile the contradiction between the return year and the lunar year, and prevent the disconnection between the lunar year and the return year, that is, the four seasons, one leap is placed every 2 3 years. The month that was adjusted or added to adjust the length of the calendar year. For example, if February of a leap year in the Gregorian calendar is adjusted to 29 days, February of that year is a leap month.

As early as the Warring States Period, there was a method of placing seven leap months in 19 years, and the month added to each leap year was a leap month. Since the Tang Dynasty, according to the 24 solar terms, the month without middle air is the leap month, and the ordinal number of the previous month is named "leap month". The lunar calendar is the traditional calendar of our country, and the traditional lunar calendar is based on the lunar calendar, and at the same time integrates the elements of the solar calendar to form a calendar, that is, the lunisolar calendar.

The Gregorian calendar is based on the return year of the Earth's revolution around the Sun. The lunar calendar is based on the waxing and waning of the moon, and the date and month are determined according to the phases of the moon. A lunar synodic month is an average of days, and the 12 synodic months are 354 or 355 days, which is about 11 days different from the solar calendar return year (about a day), and the cumulative time difference in 3 years will be more than a month.

Due to the addition of the solar calendar, the lunar calendar is a calendar that takes into account the relationship between the sun, the moon and the earth, and is a lunisolar calendar. Since the pure lunar calendar does not consider the movement of the earth around the sun, the changes of the four seasons do not have a fixed time on the lunar calendar and cannot reflect the seasons.
